We stayed at Evan's place for 4 nights.
The place is relatively easy to find, with those detailed instructions on its webpage and private messages from Evan. We arrived on a very hot afternoon but got to the place without problem. However, note that this place is on MRT line and you need to transfer to BTS line most of the time when you wanna visit sightseeing spots or go to shopping centers. Apart from that, we found the location is quite convenient.
The room is exactly as in pictures. Decent size and basic things we needed. AC worked well with an extra fan on the wall. We even felt a little cold during night.
Evan was very nice. After knowing that our flight was in the midnight, he kindly agreed to let us check out after 7pm on the last day, which greatly helped us plan our time better.
I should not forget to mention those dogs, whom we liked very much~
Overall, this was a very good experience in Bangkok and I would definitely stay again.
